Quick and easy to install, these factory-built shearwalls are a cost effective alternative to site-built shearwalls.

Strong-Wall shearwalls are narrower and available in a full array of code-listed products.

Strong-Wall Wood Shearwalls

The Strong-Wall Wood Shearwall is a prefabricated, specially designed engineered-wood panel that delivers greater lateral force resistance than most site built wood shearwalls. Features include front, back and side access holdowns and top-of-wall connection for easy installation and inspection in various framing applications. Contractors have the ability to field-trim the shearwall for custom heights and rake walls.

Steel Strong-Wall Shearwalls

Strong Frame moment frames are designed for fast and easy installation, and their simple, streamlined dimension verification and ordering process will keep your project moving forward.

Soft-Story Retrofitting

Many homes in the Bay Area, especially those with attached garages, have a condition known as soft story. This is a situation in which a living space of the house, a bedroom for example, has been built over a large opening such as a garage door. Such an opening has little or no stiffness or shear strength, hence the term “soft-story” meaning a story of a home built over a wall area that is soft in its resistance to lateral movement. Simpson Strong-Tie is a leader of state-of-the-art structural solutions specifically designed to meet the code requirements of soft-story retrofits.
